BETTA H. VANCE, OF SAN FRANCISCO, CALIFORNIA.

MOSQUITO-FOIL FOR BEDS.

To all whom it may concern:

Be it known that I, BETTA H. VANCE, a citizen of the United States,residing at San Francisco, in thecounty of San Francisco and State ofCalifornia, have invented new and useful Improvements in Mosquito-Foilsfor Beds, of which the following is a specification, reference being hadtherein to the accompanying drawings, which form a part thereof.

My invention relates to mosquito foilsfor beds in which a bag-likedevice, constructed of mesh fabric, is supported in an invertedposition, above the bed, by a skeleton frame supported by thebed-bottom, the bed lying within the mouth of the bag, adapted. to forman inclosure about the sleeper to pro tect him from mosquitoes and likeinsects.

An object of the invention is to provide a framefor supporting the bag,constructed of as few parts as possible, one that is made in such a waythat it may be readily connected-up and attached to a bed, and asreadily disconnected and folded-up into a compact form so as to occupy acomparatively small space for carrying about; a second object is toprovide for the reinforcing of the fabric at places most subject towear; a third object is to provide means whereby a sleeper may readilyenter or leave the inclosure or bag; a fourth object is to provide suchan inclosure that is comparatively roomy and one that will interfere aslittle as possible. with the free movements of the sleeper; and a fifthobject is to provide an inclosure of the character mentioned that willeffectively exclude mosquitoes and like insects.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combi-- nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed; it being understood that changes in the preciseembodiment of the invention herein disclosed can be made-within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings- Figure 1 is a view in perspective of my inventionattached to a bedbottom, also showing portions of the bedstead.

of the frame-work, also showing a portion of the bed-bottom.

Fig. 4 is a view in elevation'of another portion of the frame-work, alsoshowing a portion of the bed-bottom.

Figs. 5 and 6 are detailed views in perspective of portions of theframe-work.

Figs. 7 and 8 are detailed sectional views of certain portions of theframe-work.

Fig. 9 is a vertical section of the bag on line aa, Fig. .1, certainportions being broken away, also showingv portions of the bed-bottomwith portions of the latter in section.

Fig. 10 is a fragmentary vertical section of the head end of the bag,also showing fragments of the bed-bottom. Fig. 11 is a fragmentaryvertical section of the foot end of the bag, also showing fragments ofthe bed-bottom.

Fig. 12 is a fragmentary vertical section ofthe bag, showing a sectionof reinforcing fabric sewed onto the inner side of one of its uppercorners.

Note: In Figs. 9, 10, 11 and 12, where portions of the bag are shown cutaway, the oblique shading occurring between the paralleling lines wouldappear to indicate cuts through solid instead of open-mesh materials, 1tis intended, however to be illustrative of cuts through the latter andof which materials the bag is constructed.

Like numerals of reference designate like parts throughout the severalviews. L

1 designates the foot end and 2 the head end of a common bedstead of themetal type, which supports a bed-bottom comprising cross-pieces 3 and 4,side pieces 5, and spring wires 6.

7 designates uprights which form a portion of the head end division ofthe frame-work. Each of said uprights consisting of a lower section 8and an upper section 9. The lower section comprising a pair of flexiblerods twisted together as at 10, arms 11 extending outwardlyapproximately at right angles with the axis of said section and havingtheir free ends spaced apart and terminating in eyes 12 through whichextend fastening devices 13 for securing said arms to the cross pieced,and upwardly extending mem bore 14 provided at their fre'eends with eyes15, the axis of the eyes extending parallel with the axis of saidsection. 1 The upper 9 comprising a of more or'dess 7 together and bentinto a depending hook 16,

"of said" supporting-rods an intermediate off-set portion 17, anddownwardly extending members 18 slidably extending through the eyes 15and provided at their free ends with eyes 19 through which slidablyextend the members 14 of the lower section 8. The axis of the eyes 19extending parallel with the axis of the eyes 15.

It is-intended'that'the' section 9 shall be slidable longitudinally uponthe lower section 8, whereby the former may be adjusted vertically, andalso" intended that said sections shall be slidable longitudinallyrelatively to each other in order that the uprights may becontractedlongitudinally for packing more compactly when removed from thebedbO'ttOm.

20 is a ring-like ferrule encircling the rods 18 below the off-set 17and slidable on said rodswhen-they are-comparatively close together,-and is adapted to be moved downwardly upon said rods to contract themlaterally relatively to each other, when it is desired to arrest theirdownward movement through the eyes1 5: (See Fig. 7

(One of the uprights 7 being disposed at each end of thecross-pie'ee 4,in such a position so'that it will face diagonally across the 'bedatanangle of about 45 degrees from said cross-piece, while the third oneof the said uprightsis secured to the cross-piece at a point thereonabout equally distant from either end, and is so positioned that it willface across the bed along aline running parallel with its sides.

21 designates uprights comprising each a pair of vertically extendingmore-or-less flexible rods 22 joined together at. their upperendsandibent'into a depending hook 24, a twisted together section 23 andoutwardly' extending arms 25' having their ing; them to the; cross piece3.

The uprights 21 are adapted to be disposed upon the cross-piece 3 andpositioned thereon relatively to the bed, at points and in positionssimilar to the points and positions occupied by the uprights 7 on thecross-piece 4. f

26 designates the outer. sections and 27 the inner sections, ofsupporting-rods connecting together'the' upper ends of the outeruprights and the middle upright of each division of the framework. Eachsection comprising a straight rod provided at one en'd with a hook 28'and at the other end with an eye 29 through whichslidably extends anintermediate portion of the cooperating or oppositesection. The hooks 28of the outer sections 2:6 are adapted to be supported by the hooks 16and. 24 of the outer uprights, and the hooks 28 of the sections 27 areadapted to be supported by the rings 30 supported by the hooks 16 and 24of the middle uprights.

The sections 26 and 27 are adapted to slide longitudinally past oneanother through the eyes 29, whereby the connecting-rods may be adjustedlongitudinally to meet the varying distances at which the uprights maybe set apart from each in order to meet the requirements of beds ofvarious widths, and also so as to make them contractably longitudinallythereby permitting them to be bundled up more compactly fortransportation purposes.

31 are flexible supporting-cables, constructed preferably of ordinarycords or tape of sufiicient strength for the purpose for which they areadapted, however, .if so desired, wires or wire-cables can besubstituted. Each of said cables have one end secured to one of saiddivisions of the frame adjacent the top ends of the outer or enduprights and the other end secured to the top end of the outer or enduprights of the other division.

32 designates the upper and closed end,

33the foot end, 34 the head end and 35 the sides of a four-sidedcovering bag open at its lower end and constructed of mosquito-bar orlike mesh fabric of a mesh sufficiently small to prevent the passingtherethrough of mosquitos and like insects. Into said bag from the lowerand open end thereof'is adapted to project said frame for extending andsupporting it. The corners in the upper end of the bag being adapted tohang upon the top ends of the outer uprights of each division. Theintermediate sections of the upper end of'the bag being supported by thecables 31.

' Along the margin of the opening in said lower end of the bag is sewedas at 37 a border strip 38 constructed of smaller mesh andstronger andmore wear-resisting fabric than the bag proper. The free edge of saidborder strip is confined between the bedbottom and the bed' adjacent themargins thereof thereby confining the bag adjacent its open end closeupagainst the bed, said bed lying substantially within the bag.

39 is an'opening extending through one of the sides 35 intermediate itsends, adapted as a passage-way for the occupant of the bed for enteringor leaving the bag. Said opening 39 extending vertically from the upperend of the bag downwardly to the border strip 37, while horizontally itextends through the middle section of the side at a distance inwardlyfrom either end thereof. v

' 40 designates a curtain preferably constructed of the same class ofmaterial as the bag and having its upper edge sewed thereto above theopening 39. Said curtain being adapted to over-hang said opening and toform means for closing same and is provided adjacent its lower edge withbuttonholes 42 adapted to be engaged by buttons 43 spaced along the bagbelow the opening.

It is preferable to make said curtain Wide enough so that its side edgesmay over-lap comparatively Wide portions of the side 35 adjacent thesides of the opening 39, whereby said. curtain may form a more effectiveclosure therefor when it is let down as far as it will go. and buttoned.

36 designates pieces of relatively smaller meshed and morewear-resisting fabric than constitutes the body of the bag, sewed ontothe inner sides of the upper corners thereof and adapted to protect itagainst wear-andtear of the frame. If desired, said pieces 36 may bemade of material other than fabric.

44 designates the bed.
